Boeing (BA-0.9%) may be saddled with another headache once the investigation into its Dreamliner battery mishap comes to a close. Depending upon the findings, Japan's All Nippon Airways is prepared to recoup from BA whatever damages it suffers from flight cancellations and other costs caused by the grounding of its jets, which could leave the door open to other airlines doing the same. ANA is BA's biggest Dreamliner customer, with 17 of the jets in its fleet, and has so far canceled 459 flights this month because of the grounding.
